Ultra Low-Power µP Supervisory Circuit

1 General Description

The AS1901/2/3 family is an ultra low-power supervisory

circuit device.

2 Key Features

Low 230nA (typ) Supply Current

Precision Monitoring of 2.5-, 3-, and 3.3V-Power

Supplies

The device can be used to monitor the supply voltage of

digital systems and microprocessors and initiate a reset

when the voltage goes below a predefined threshold.

The duration of the reset is 5/20/100/500ms (typ.) after

the supply voltage has risen above the threshold.

Supply Voltage Range: 1.0 to 3.6V

Reset Threshold Range: 2.2 to 3.1V

Available in 3 Versions:

The AS1901/2/3 exhibit excellent reliability and can

reduce application costs by eliminating all external com-

ponents.

- AS1901 Push Pull RESETN

- AS1902 Push Pull RESET

- AS1903 Open Drain RESETN

The device is available with different output drivers:

The AS1901 has a push-pull driver with an active low

reset.

4 Time-Out Periods Ranging from 5 to 500ms

Detection Voltage Accuracy: 1.5%

Temperature Range: -40 to +85°C

Package: SOT23-3

The AS1902 uses the same output stage as the

AS1901, but has an active high reset.

The AS1903 has an open drain output with active low

reset.

All devices operate down to a voltage of 1V.

Pin Compatible to MAX6326/6327/6328

The reset thresholds are factory-trimmable between

2.2V and 3.08V in steps of approximately 100mV.

3 Applications

Each device of the AS1901/2/3 family is offered with four

time-out periods of 5/20/100/500ms.

Computers

The extremely low current consumption of only 230nA

(typ) at 3.3V makes the device ideal for use in portable

applications.

Intelligent Instruments

Controllers

All devices are available in a 3-pin SOT23 package.
